Mhando dzakasiyana dzemapombi epaipi muindasitiri yemafuta uye gasi

Muindasitiri yemafuta uye gasi, mhando ina dzecasing dzinowanzo shandiswa:

1.Conduit: Conduit ndiyo yekutanga kotoni yakaiswa kutsigira huremu hwechibhorani chekuchera uye kudzivirira chibhorani kubva pakudonha panguva yekuchera.Conductor Casing: Kazhinji, conductor casing ndiyo yakakura dhayamita casing inoshandiswa mukuchera mabasa.Inokura muhukuru kubva pa20 kusvika ku42 inches mudhayamita.Conductor casing inowanzogadzirwa neakaderera-giredhi kabhoni simbi, senge J55 kana N80, kupa kugadzikana panguva yekutanga yekuchera chikamu.

2. Surface casing: ndiyo yechipiri casing yakaiswa kuti ipe dziviriro yemvura yakachena uye kudzivirira kusvibiswa.Iyo dhayamita yaro inowanzova yakakura kupfuura iyo yeimba conductor.Surface Casing: Surface casing ndiyo yekutanga casing yakaiswa mutsime mushure mekuboora gomba kondakita.Inopa dziviriro yemvura yakadzika pasi uye inoparadzanisa maumbirwo epamusoro.Iwo anowanzo shandiswa saizi yekumusoro casing ndeye 13⅜ kusvika 20 inches mudhayamita.Material mamakisi ekumusoro casing anogona kusanganisira kabhoni simbi mamakisi seJ55, K55, N80, kana yakakwirira-simba zvinhu seL80 kana C95.

3. Intermediate Casing: Iyi casing inoiswa pakadzika kwakasiyana zvichienderana nemamiriro etsime uye inoshandiswa kuchengetedza tsime kubva pakugadzira zvinwiwa uye kumanikidza.Inopa humwe hutsigiro uye kuzviparadzanisa kune tsime.Yepakati Casing: Yepakati casing yakaiswa pakadzika yepakati uye inopa rumwe rutsigiro kutsime.Yepakati casing saizi inotangira pa7 kusvika 13⅜ inches mudhayamita, zvichienderana nekugadzirwa kwetsime.Material mamakisi epakati casing anogona kusanganisira L80, C95, kana epamusoro-simba mamakisi seT95 kana P110.

4. Production Casing: Iyi ndiyo yekupedzisira casing yakaiswa mutsime mushure mekuchera kwapera.Inopa kurongeka kwechimiro kutsime uye inoparadzanisa nzvimbo yekugadzira kubva kune yakatenderedza maumbirwo kudzivirira kudonha uye kuchengetedza zvakanaka kubereka.Aya marudzi mana emakesi anowanzo shandiswa muindasitiri yeoiri negasi, asi misiyano inogona kuvepo zvichienderana nemamiriro chaiwo etsime uye zvinodiwa zvekutonga.Yepakati Casing: Yepakati casing yakaiswa pakadzika yepakati uye inopa rumwe rutsigiro kutsime.Yepakati casing saizi inotangira pa7 kusvika 13⅜ inches mudhayamita, zvichienderana nekugadzirwa kwetsime.Material mamakisi epakati casing anogona kusanganisira L80, C95, kana epamusoro-simba mamakisi seT95 kana P110.

Izvo zvakakosha kuti uzive kuti saizi yekasi uye magiredhi ezvinyorwa anogona kusiyana zvichienderana nezvinodiwa nematsime uye zviyero zvedunhu.Akasiyana-siyana alloys, corrosion-resistant zvinhu, uye zvishongedzo zvinogona zvakare kushandiswa zvichienderana nemamiriro emutsime, senge nharaunda yegasi rakavava kana matsime ekudzvinyirira / kutonhora kwakanyanya.
